Import contacts list requested IP address

Import contacts list requested IP address

Hi Zoho team,

I'm finalizing the setup of Zoho Campaigns and I would like to import a list of users/participants with an Excel Sheets. But by default, it's compulsory to provide the IP address of our users/participants. 
On our side, providing the IP address to any third-party/providers does not correspond to our policy privacy regarding personal data. This list is coming from MailChimp and we want to cancel our subscription of Mailchimp to deploy all our marketing campaigns in Zoho Campaigns. All the contacts has expressed their consent (we have the date/time of consent for each contact). But currently, we are blocked because of this issue.

Is there any way to solve this problem?
Thank you very much.
